CANE-MILL.

Application filed July 24,

To 111/ (I'll/U111; it may concern.-

Be it known that I, JUDsON BUCHANAN, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of 'lennessee, have invented a new and useful Improvement in Cane-Mills, of which the following a specification, reference being had to the accompanying drawings.

My invention relates particularly to canemills comprising two upright rolls between which the cane-stalks are crushed.

The object of the invention is to produce a mill which is light and simple in construction and at the same time adapted to perform a large amount of work.

In the accompanying drawings, Figure 1 is a side elevation of a cane-mill embodying my improvement. Fig. 2 is a plan of the same mill. Fig. 3 is an upright cross-section of the juice-pan. Fig. 4 is a section on the line 4 at of Fig. 2 looking toward the right. Fig. 5 is a longitudinal upright section on the line 5 5 of Fig. 2.

Referring to said drawings, 1 1 are upright posts which are preferably secured by extending their lower ends into the ground. To opposite sides of said posts are secured four horizontal bars 2, said bars being arranged in horizontally-opposite pairs and joined to the posts by bolts 3, extending horizontally through said bars and said posts. Said bars are preferably composed of steel and in form they are preferably I- beams, in order that the greatest strength may be had for a given cross section. WVasher-plates 4 surround the bolts 3 at each end of the latter and rest in the outer chan nels of the bars 2. In the manufacture of such mills I have formed said bars out of steel plow-beam material, as shown in the drawings.

Upon each pair of bars 2 are mounted a pair of bearing-blocks 5. Each such bearing-block has a horizontal aperture 6, through which one of the bars 2 extends. The righthand bearing-blocks 5 are slidable on said bars, while the left hand of said blocks are secured immovably to said bars by means of bolts 7, extending transversely through said bars and through ears 8, projecting laterally from said bearing-blocks. The outer end of each bearing-block is penetrated by an aperture 9, which is horizontal and parallel to the Specification of Letters Patent.

bars 2. Bolts or rods 10 extend parallel to the bars 2 and through the apertures 9 of adjacent ends of said bearing-blocks. The function of said. bolts is to adjust the distance between the right-hand bearing-blocks and the left-hand bearing-blocks. Each bearing-block has an upright bearing 11 to receive one of the shafts or axles of the rolls. Each of said bearings is preferably provided with a lateral half-tubular recess 12 for receiving a half-tubular bushing 13.

The shaft 14 rests in the bearings of the left-hand bearing-blocks. Between said bearing-blocks said shaft is surrounded by the roll 15 and the spur gear-wheel 16, both of which are secured immovably upon said shaft. At its upper and lower ends said roll has annular flanges 17. At its upper end the shaft 14 extends above the upper bearing-block 5 and supports a crosshead 18, to which an ordinary sweep is to be attached for hitching one or more horses to rotate said roll.

A shaft 19 rests in the bearings of the lefthand bearing-blocks and is surrounded by the roll 20 and a spur gear-wheel 21, both socured immovably to said shaft. The length of said roll (in the upright direction) equals the space between the flanges 17, and said roll extends between said flanges. The rolls 15 and 20 are of equal diameters, and the spur gear-wheels 16 and 21 are of equal diameters and intermesh, so that when the left-hand shaft is rotated by the application of power to said cross-head the two rolls must rotate synchronously and in opposite directions, the opposing surfaces traveling in the same direction and at the same velocity.

It will be observed that by means of the bolts 10 the space between the rolls 15 and 20 may be varied.

A mouthpiece or feed-guide 22 is supported upon the front bolts 10 midway between the bearing-bocks and horizontally opposite the rolls 15 and 20. In the form shown in the drawings the lowerend of said feedguide has ears 23 surrounding the lower front bolt 10, while the upper end of said feed-guide has a metallic strap-form springcatch 23, extending upward and over the upper front bolt 10. Said catch may be sprung upward and released from said bolt and the upper end of said guide swung outward and downward, the guide turning upon the lower front bolt 10. During the operation of the machine the cane-stalks are fed endwise through said guide.

A juice-pan 24 is to be secured in any suitable manner beneath the rolls and to receive the juice expressed from the stalks passing between said rolls. In the form shown in the drawings said pan has four 10 sheet-metal hooks 25,rising from the bottom of the pan and extending over the lower bolts 10. This is a simple and economical construction for the support of said pan, and it permits the ready removal of the pan by 1 5 springing the upper ends of the hooks laterally until they are released from the bolts. At any desired point the bottom of said pan is provided with a spout 26 for the discharge of the juice.

20 The bearings 11 of the lower bearing-block are preferably closed below, as shown in Fig. 5, in order to avoid the dripping of lubricating-oil into the juice-pan.

I claim as my invention 2 5 1. In a' machine of the nature described, the combination with two upright, parallel rolls, a bearing-block at each end of each of said rolls, horizontal parallel bars extending through and supporting said bearing-blocks,
